The Gdf1 Knockout Hepa 1-6 Cell Line is a CRISPR/Cas9-edited knockout cell line generated from mouse Hepa 1-6 hepatoma cells. This model disrupts the Gdf1 gene, encoding Growth Differentiation Factor 1 (GDF1), a TGF-beta superfamily ligand essential for left-right axis determination and SMAD2/3 signaling via ALK4/ActRIIB receptor complexes. With endogenous GDF1 eliminated, this cell line enables precise investigation of GDF1-dependent pathways, including SMAD2/3 phosphorylation and Pitx2 induction, in a hepatocellular context. It is ideal for studies of TGF-beta signaling, left-right determination, and hepatocyte-specific signal transduction using assays such as Western blot and luciferase reporters.

The Gdf1 Knockout Hepa 1-6 Cell Line is a CRISPR/Cas9-edited knockout cell line generated from the mouse Hepa 1-6 hepatoma line. This product features targeted disruption of the Gdf1 gene, which encodes Growth Differentiation Factor 1 (GDF1), a TGF-beta superfamily ligand critical for left-right axis determination. The knockout provides a stable loss-of-function model for studying GDF1-dependent signaling, enabling dissection of its role in cellular processes.
The host Hepa 1-6 cell line is a mouse hepatoma derived from the C57L strain, retaining key characteristics of liver parenchymal cells including metabolic and detoxification functions. This hepatic origin offers a physiologically relevant system for investigating TGF-beta superfamily signaling in the context of hepatocyte biology, liver metabolism, and hepatocellular carcinoma research.
GDF1 functions as a secreted ligand that assembles receptor complexes of ALK4 and ActRIIB, with the co-receptor Cripto. Ligand binding induces phosphorylation of SMAD2 and SMAD3, which upon SMAD4 binding, translocate to the nucleus to regulate target genes such as Pitx2. Upstream, Gdf1 expression is controlled by Nodal and FoxH1. Knockout of Gdf1 eliminates this signaling axis, blocking SMAD2/3 activation and downstream transcriptional events.
In the hepatocellular context of Hepa 1-6 cells, the Gdf1 knockout allows exploration of TGF-beta superfamily signaling beyond embryonic left-right determination. Although GDF1 is primarily associated with developmental patterning, TGF-beta pathways play important roles in liver physiology, fibrosis, and cancer. This cell line enables distinction of GDF1-specific effects from those of related ligands, shedding light on its potential non-developmental functions in hepatocyte signaling.
Researchers can employ this knockout cell line for diverse functional studies, including analysis of SMAD2/3 phosphorylation by Western blot, measurement of Pitx2 expression via RT-qPCR, and assessment of pathway activity using SMAD-responsive luciferase reporters. Co-immunoprecipitation can probe receptor-ligand interactions. The Gdf1 Knockout Hepa 1-6 Cell Line is an essential tool for dissecting TGF-beta signaling, left-right determination, and hepatocyte signal transduction.
